Can a portable power station run a mini fridge (compact, ~3 cu ft)?

Yes. All 15 portable power stations we track can run a mini fridge (compact, ~3 cu ft), for about 9.2 h (EcoFlow RIVER 3 Plus) to 4.8 days (Anker SOLIX F3800) on a full charge.

How these runtimes are calculated: runtime = usable capacity ÷ average draw of 25 W (running draw is 75 W, but a compressor cycles on and off, so the daily energy use averages lower). Usable capacity is an independent test's measured figure, or 80% of rated capacity where none exists, marked "(est.)". A model must also carry the running watts continuously and the startup peak within its surge rating. The same formula applies to every model; see the methodology.

Light load: at 25 W the station's own consumption matters, so expect less than shown, especially overnight. Independently measured idle draw (AC inverter on, nothing plugged in): EcoFlow DELTA 3 Classic 17 W, Anker SOLIX S2000 2.7 W, EcoFlow DELTA 2 Max 13.6 W, Anker SOLIX C2000 Gen 2 18 W. Using a DC or USB output instead of the AC inverter, where your device allows it, avoids most of this loss.

What size do you need?

What size power station do I need for a mini fridge (compact, ~3 cu ft)?

Look for at least 75 W of continuous AC output and 500 W of surge. For capacity, a mini fridge (compact, ~3 cu ft) averages about 25 W, so 8 hours needs roughly 250 Wh of rated capacity and 24 hours roughly 750 Wh, assuming 80% of rated capacity reaches the outlets.

How long will a 1,000 Wh power station run a mini fridge (compact, ~3 cu ft)?

About 32 h for a generic 1,000 Wh unit, if its inverter can handle the 500 W startup surge: roughly 800 Wh (80% of rated) reaches the outlets, divided by an average draw of 25 W. Measured models of this size vary; see the table above.

Which power station can run a mini fridge (compact, ~3 cu ft) for a full day?

Of the 15 models we track, the smallest that runs a mini fridge (compact, ~3 cu ft) for 24 hours on one charge is the DJI Power 1000. Larger models run it longer; see the table above.

What a mini fridge (compact, ~3 cu ft) draws

Running watts	75 W^[source]Midpoint of Champion's 50-100 W 'Mini fridge/cooler' running range.
Startup (surge) watts	500 W^[source]Midpoint of Champion's 400-600 W 'Mini fridge/cooler' starting range (compressor start).
Energy per day	0.6 kWh^[source]Median annual energy use of the 700 ENERGY STAR certified compact refrigerators with 2.5-3.5 cu ft total volume in EPA's certified-refrigerators data set, retrieved 2026-10-18: 220 kWh/year, converted to 220 / 365 = 0.6 kWh/day. Middle half: 215-260 kWh/year (0.59-0.71 kWh/day).
Average draw used above	25 W
Voltage	120 V

Compressor cycles on and off, so daily energy is used for runtime rather than running watts.
